齿轮座的人字齿轮是轧钢设备的关键备件之一。每套造价低则几万元,高则几十万元。冶金设备工作者对这些齿轮的设计、制造、使用和维修都很重视。随着设计、制造、使用和维修水平的提高,其使用寿命也不断提高。我厂850初轧机齿轮座的人字齿轮已连续使用22年,500中型轧机齿轮座的人字齿轮已连续使用18年,目前仍可继续使用,但其它五套小型轧机齿轮座的人字齿轮使用寿命都在五年以下。本文拟通过对这几套齿轮座运行情况的简要分析,提出提高这类齿轮使用寿命的若干措施。
Gear seat herringbone gear is one of the key spare parts for rolling equipment. Each set of low cost is tens of thousands of dollars, high is several hundred thousand dollars. Metallurgical equipment workers attach great importance to the design, manufacture, use and maintenance of these gears. As the design, manufacture, use and maintenance of the level of improvement, its service life is also rising. The mill gears of our mill 850 have been used continuously for 22 years. The herringbone gears of the 500 medium-sized mill stand have been used continuously for 18 years and can still be used at present. However, the other five sets of small mill gear stands have herringbone gears Life is less than five years. This paper intends to run through these sets of gear box a brief analysis of the situation, put forward some measures to improve the service life of such gears.
